ABSTRACT:
Three new species of Xanthosoma (X. anisotomum E.G.Gonc¸., X. pedatisectum E.G.Gonc¸. and X. rubrispathum E.G.Gonc¸.) and two new species of Caladium (C. intermedium E.G.Gonc¸. and C. amazonicum E.G.Gonc¸.) are described. These new species are all illustrated and compared to their closest relatives. Caladium intermedium is noteworthy in appearing intermediate between Caladium and Scaphispatha, turning the boundaries between both genera rather complex.
